Cornelius R-404A REFRIGERANT service manual Installing Unit, Installing Leveling Legs

Page 16

Locate the Unit so the following requirements are satisfied.

1. Close to a filtered plain water inlet supply line with a minimum water pressure of 12-psig.

NOTE: The FCB Dispenser refrigeration system is equipped with a condenser coil that is cooled by two condenser coil fans. Circulating air, required to cool the refrigeration system’s condenser coil, is drawn in through the grilled panel on the right-hand side and is exhausted out through the opposite side grilled panel. Restricting air circulation through the Unit will decrease its cooling efficiency.

2.When installing Unit in it’s operating position, do not allow obstructions to block sides, top, and front of the Unit which will block off cooling air intake to the inside of the Unit. Air flow through the Unit must be present to provide adequate cooling for the refrigeration system.

CAUTION: Do not place or store anything on top of the Unit.

Locate the Unit to provide the following clearances:

Top of Unit	Open (24-inches min.)
Back side	0-inches
Sides	6-inches (min)
Front	Open

INSTALLING UNIT

CAUTION: This Unit is intended for indoor installation only. Do not install this Unit in an outdoor environment which would expose it to the outside elements.
